Leviticus 24:14-16

14 aBring out of the camp the one who cursed, and let all who heard him blay their hands on his head, and let all the congregation stone him. 15And speak to the people of Israel, saying, Whoever curses his God shall cbear his sin. 16Whoever dblasphemes the name of the Lord shall surely be put to death. All the congregation shall stone him. The sojourner as well as the native, when he blasphemes the Name, shall be put to death.
